The hook:

Thread:

Uni 6/0 or 8/0 Black

Body:

Davy's Bug Dub hare mix (Veniards)

Wing:

Sparse bunch of comparadun or fine natural deer hair (a wee variation from the Irish original but something that works well for me, trout take as either a midge or even a small dark sedge helping make the fly more versatile)
